Description

Link to discussion.
#15540

.Net Maui apps crash on the iOS 17 beta. iOS 17 is being released in September but some people are installing the beta now. Can we have some indication of when this will be fixed? Will there be a .NET Maui 7 release to address it or will it only be addressed in November with the .NET Maui 8 release?
I assume there's also a dependency on XCode 15?

We'll fix this in dotnet/macios#18621, and backport the fix to .NET 7 so that the next service release will contain it.

[tools] Always link weakly with NewsstandKit. Fixes #18606. (#18621)
82a5174 
It seems that Apple will completely remove the NewsstandKit framework from iOS 17.

This poses a problem for existing apps that link with NewsstandKit: they will
crash at launch.

Solve this by always linking weakly with the NewsstandKit framework; this way
any apps that link with it will keep working if the framework ends up being
removed by Apple.

Fixes #18606.
Fixes dotnet/maui#16316.

We'll fix this in xamarin/xamarin-macios#18621, and backport the fix to .NET 7 so that the next service release will contain it.

@rolfbjarne I guess this didn't make it into 7.0.307? Have just updated and rebuilt my project but it is still crashing at launch on iOS 17.

Correct, it was fixed too late for this week's release, it'll be in the next release.

@rolfbjarne Any word on when that'll be?
iOS 17 release is scheduled between September 13, and September 21, 2023. We can't have our apps just stop working out of the blue.

Is there a way to somehow fix this without having to wait for the official release?

If all goes well in the next service release.
